Why Upgrade?

upgrade your current storage capacities with an ST4000NM0023 Seagate 4TB 7200RPM 6Gb/s 128MB 3.5-inch SAS hard drive. This disk drive delivers higher capacity and drive speeds than a traditional solid-state drive without sacrificing performance or reliable data access.

While the drive’s external architecture closely mimics its predecessor, it has a few key differences that contribute to greater overall performance. For example, the hard drive body contains various thermal pads that help keep the unit cool and dissipate heat.

Although the Constellation ES.3 is available with a SAS or SATA interface, the SAS hard drive is better for mission critical environments due to its High Availability features, like the multi-path and dual-port technologies.

Seagate also significantly improved performance with this model compared to the previous Constellation ES.2. While the ES.2  had a data rate of 155 MB per second, the Constellation ES.3 has a 175 MB per second data rate, which is an 11% improvement.

These various features, combined with the SAS hard drive’s improved power consumption and slim form factor, make the ST4000NM0023 Seagate 4TB 7200RPM 6Gb/s 128 3.5” SAS hard drive a reliable hard drive.
